•        This plot shows the performance of learning algorithm for 1 serve over 100,000 trials
•         Plota  where
•   a=1 refers to successful shots => reaching the ball
•   a=2 refers to completely successful shots => hitting a correct shot as well
• Here
• Gamma = 0.9
• Lambda = 0.95
• Reward Function  = 2  for complete success
                                                 = 1  for partial success
                                                 = -1 for failure
                                                 = 0 otherwise
